Keep the linkage lubed, the throw-off won't break down anytime soon. In some cases there are some very good reasons to switch the throw-out every second impression. One of the first tricks of the trade that I ever learned from a seasoned pressman was to double roll a platen jobber for dies with large areas of coverage.

I have an old press (I've had it since the 1960s) which I use for a variety of work, and have treadled as many as 5000 pieces at a time. You do get into a rhythm with the process, and I can stop the press very rapidly by just holding down the treadle. It is however, a light weight press (Kelsey Union Rotary) and stops at my command easily.

It would be much better to slow down the press to a manageable speed and establish a rhythm not involving the use of the left arm running the throw-off.
